NAME
cacos, cacosf, cacosl - complex arc cosineSYNOPSIS
#include <complex.h>double complex cacos(double complex z);
float complex cacosf(float complex z);
long double complex cacosl(long double complex z);
Link with -lm.
DESCRIPTION
The cacos() function calculates the complex acos(). If y = cacos(z), then z = ccos(y). The real part of y is chosen in the interval [0,pi].One has cacos(z) = -i clog(z + csqrt(z * z - 1)).
